CASH-REGISTER.

Specification of Letters Patent.

Patented May 21, 1912.

To all whom ir' may concern:

Be it known that I, VILLIAM H. MUZZY, a citizen of the United States-residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Casli-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers, and has more particular relation to improvements in machines of the so called multiple drawer type in which an independentdrawer or receptacle is provided for each clerk.

The object of the invention is to provide improved mechanism whereby the movement of any particular cash receptacle will select its respective clerks' designating element of the register.

A further object is to provide means whereby the opening of any one of the clerks receptacles will bring into operation a motor for operating the register.

Vith these and incidental objects in View, the invention consists in certain novel features of construction and combinations of parts, t-he essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 represents a vertical transverse section through the devices embodying the invention, applied to the type of machine shown in Patent No. 580,378, issued April 13th, 1897 to Cleal and Reinhard. Fig. 2 represents an end elevation of the same partly broken away. F ig. 3 represents a similar view taken from t-he opposite end of the machine. Fig. 4c represents a diagram of the electrical connections. Figs. 5 and 6 represent, respectively, a side elevation and a top plan view of one of the magnetically operated latches. Figs. 7 and 8 represent, respectively, a detail side elevation, and a detail front elevation, of the wiper arm for returning all of the automatic keys to their normal latched positions.

In machines of the type known as multiple drawer machines it has customarily been the practice to allot a single compartment, or a single cash drawer, to each clerk;-

and to release this cash drawer, or drawers, by first operating certain elements in connection with the register andrthen setting in motion the operating mechanism of the register, which, after a predetermined period, would eifect the opening or release of the cash receptacle.

1t has been customaryl in machines of this type, to have certain functions of the register proper fully performed before the cash drawer was opened, so that access may be had to the cash therein. The idea of this structure was, that no clerk should have access to his cash drawer to make change until the process of registration was so far advanced that he could take no advantage of a previous registration or indication, and so that there would be no retracting or leaving the subsequent registration in its partially completed state.

In the present invention the cash drawers are unlatched and drawn out by hand, although it will of course be apparent that springs may be inserted behind the cash drawers so. that when they are unlatched they will be automatically forced out of the casing. Vhen any one of the drawers is so drawn out of the casing, one of a series of circuits is completed; this circuit releasing the particular clerks key corresponding to the cash drawer withdrawn and at the same time completing the circuit of an electric motor connected to drive the machine. After this circuit has been once. completed by the opening of the drawer, a shunt circuit is closed whereby the closing of the drawer again will not break the circuit until after the motor has made a complete operation.

As many of the details of the present machine are fully shown and described in Letters Patent No. 580,378, no detailed description of the indicating and printing mechanisms will be given, but reference to said patent for such description may be made.

Referring to Fig. 1 in the accompanying drawings, it will be seen that each of the clerks keys l is normally latched in its outer position by a projection 2, fastened to an armature 3 of a magnet 4, engaging a notch 5 formed in the outer end of each of the keys 1. The clerks keys, when released, are forced inwardly by springs 6 surrounding said keys, and abutting against pins 7 carried by the keys, and against a plate 8 through which the keys slide. A hood 9 covers the outer ends of the keys and the magnets so as to prevent manipulation of said keys.

The keys 1, when released project into the path of a pawl 16 carried by an arm 16a pivotally secured to a segment 11 which is .loosely mounted upon a rock shaft 12. A

cam 13 secured to the rock shaft is arranged to be moved in the direction of the arrow a distance of about 90 degrees upon the beginning of the operation of the machine, and upon its return a shoulder 14 formed upon the cam engages a similar shoulder 15 formed upon a slide 10 supported by the lower ends of two arms 10a, which are pivoted at their upper ends to the segment 11, and carry said segmentwith it. An upwardly extending portion of the arm 16 is bifurcated and straddles a pin 10b projecting from the slide 10. A spring 16b is seated in the rear end of the arm 16a with the free end abutting against a flange 16c projecting from the segment 11 and thereby forces the shoulder 15 into engagement with the shoulder 14 whenever the latter presents itself. These shoulders are disengaged by the pawl 16 contacting with the inner end of one of the keys 1 which will rock the arm 16a and thereby move the forward end of the slide 10 into one of the recesses 2OEL formed in a plate 20b and positively lock the segment 11, to which the slide is attached, from further movement.

Fastened to the rock shaft 12 is an arm 17 having pivoted to its outer end a pawl 13, which is free to rock about its pivotal point, against the tension of a coil spring 19, in one direction, but is prevented from moving in the opposite direction by a pin 2O with which the tail 21 of the pawl contacts. This arm and pawl are mounted upon the rock shaft relative to the segment 13, in such a manner that immediately after the shoulders 14 and 15 are disengaged by the pawl 16 contacting with the inner end of a depressed key, the beveled end of the pawl 13 will contact with the pin 22 of the depressed key and force said key outwardly against the tension of its spring until it is latched in its outer position by the projection 2 of the armature 3.

As the armature and magnet for each key are similar, a description of one will suflice for all. Referring to Fig. 1 it will be seen that each magnet 4 is suitably supported upon a bracket 23 within the hood 9, and

projecting from the magnet (Figs. 5 and 6) is a pair of uprights 24 equipped with guide lingers 25 extending into cutI out portions 26 of the latch projection 2 of the armature 3. The projection 2 is normally forced into engagement with the recess 5, formed in its companion key 1, by a coil spring 27 surrounding said projection, one end of which contacts with a pin 28 while the outer end abuts against the lower guide lingers 25 formed upon the uprights 24.

The cash receptacles 28, of which there are as many as there are clerks keys but of which three only are shown, are in the form of drawers and each is provided with a pull 29 secured to its front end. A latch 30 in the form of a bell crank lever is suitably mounted within a cut-out portion 31 of the forward part of each cash drawer. The upper end of the vertical arm of each bell crank is normally forced into a recess 32 of a partition 33 by a leaf spring 34 secured within the cut-out portion 31, so as to prevent the opening of the cash drawer accidentally. The horizontal arm of the bell crank projects forwardly into the pull 29, and is arranged to be raised .by the fingers of the operator so as to withdraw the vertical arm from out of the recess 32 against the tension of the spring 34, and thereby allow the withdrawal of the cash drawer.

Upon the rear end of each cash drawer is pivotally mounted a spring drawn hook lever 35, the hook end of which, when the cash drawer is in a closed position, engages a pin 36 mounted upon a spring pressed lever 37 pivotally mounted upon the partition 33. The upper end of the lever 37 is provided with a V shaped insulating block 3S which normally holds the contact plates 39 apart. The plates are suitably mounted upon a false back and are connected to binding posts 40. Upon the opening of a cash drawer the hook end of the lever 35 will engage its pin 36 and rock the lever 37 about its fulcrum, against the tension of a spring 41. rThe rocking of the lever 37 will withdraw the block 33 from out of engagement with the spring contact plates 39, allowing them to sp1-ing together to close a circuit as hereinafter' more fully described. As the cash drawer continues its outward movement the pin 36 will pass below the plane of movement of the hook lever 35 and be released and forced back to normal position by its spring 41. A foot 42 limits the rearward movement of the lever 37. The spring 43 connected to the lever 35 is stronger than the spring 41, so that when the cash drawer is pulled out the lever 35 will not ride over the pin 36 without rocking the lever 37. A foot 44 of the lever 35 abuts against the rear of the cash drawer to limit the downward movement of the lever 35.

As shown in Fig. 2, a motor 46 is mounted alongside of the register, and its shaft 47 is provided at one end with a worm 48 which meshes with a worm wheel 49 mounted to rotate upon a shaft 50 suitably secured to the register casing 51. Fastened to the side of the worm wheel 49 is a gear wheel 52, which meshes with a similar wheel 53 rigidly secured to a shaft 54 that extends through the machine.l The wheel 53 meshes with another gear wheel 55 fastened to a shaft 56, which also extends through the machine. Attached to the side of the gear wheel 55 is a disk 57 equipped with a shoulder 58, which normally engages the end of a pawl 59 pivotally mounted upon the register casing and held in position by a spring 60. The pawl 59 is arranged to be drawn out of engagement with the shoulder 58 by an electromagnet 61, which attracts a soft metal plate 62 attached to the under side of said pawl when said magnet is energized as hereinafter described. The magnet is mounted upon a bracket 63 attached to the register casing 51.

As above described, the shaft 54 extends through the machine and rotates in the direction of the arrow, Fig. 1. Fastened to this shaft 54 is a disk 64 provided with a cut-away portion 65, which as the disk is rotated permits the contact plates 66 to separate and temporarily break the circuit at this point. The contact plates 66 are mounted upon opposite sides of a fiber plate 67 and are provided with binding posts 68.

,When any one of the cash receptacles is withdrawn, an electromagnet 69, Fig. 1, is energized and attracts an armature 70 pivotally mounted at 71 against the tension of its spring 72. rlhe rearward end of the armature 70 as it is attracted by the magnet 69, contacts with a conducting strip 73 suitably secured to the register frame, and forms a shunt circuit so that when the lever 37 liies back by means of its spring 41 and separates the contact plates 39, the circuit will still be made as hereinafter described.

The differential movement of the segment 11 is transmitted to the clerks indicator 74 by an intermediate gear 75 and a gear 76 secured to said indicator. The intermediate gear 75 is fastened to one end of one of a series of nested sleeves 77 which surround the shaft 56, while the other end, Fig. 3, is provided with a type carrier 78. The extreme left hand end of the shaft 56 has rigidly secured thereto a disk 79 equipped with a cam groove 80, in which plays a pin 81 secured to the side of a. platen carrier 82. The configuration of the groove is such that upon a complete rotation of the disk 79, the platen carrier will be reciprocated twice; first to take an impression from the type carrier upon the check which is then cut off and ejected, and second to take a similar impression upon the sales strip 84. It is to be understood that the amount keys 85, Fig. 2, control the indicator and type carrier similarly to the clerks keys, all of which is fully shown and described in the aforementioned patent.

Referring now to the diagram shown in Fig. 4, the different circuits will be traced. Assuming the upper insulated block 38 shown in said diagram to be withdrawn from between the contact plates 39 by the outward movement of the cash drawer controlling said block, a circuit will be made as follows: from the battery 86, through the wire 87, to the motor 46, wire 88, through the shunt magnet 69, wire 89, lock control-4 ling magnet 61, wire 90; thence through the clerks key magnet 4, wire 91 to the contact plates 39, through the wire 92 to wire 93, contact plates 66, and through the common return wire 94 to the battery 86. As soon as the above described circuit is made, the magnet 69 will attract the armature 70 and one end of said armature will contact with the strip 73 and thereby shunt the circuit from wire 89 through wire 95 to the armature 70, strip 73, wire 96 to the wire 93, thence through the contact plates 66 to the battery by wire 94. The establishment of this shunt circuit which is of much less resistance reduces the current in the circuit previously traced so greatly as to permit the latching of the plunger 1 by its armature projection 2 and the restoration ofpawl 59 to locking position, as magnets 4 and 61 will then be unable to hold their armatures against the force of the restoring springs. The circuits for the remaining drawers will be thefsame, excepting that the individual wires 91a and 91b connect the clerks key magnets 4 to their respective contact plates 39 located in the rear of the cash drawers, and from the contact plates 39 extend wires 92a and 92b to the common wire 93.

Near the end of a rotation of the shaft 54 the notch 65, cut in the periphery of the disk 64 secured to said shaft, permits the contact plates 66 to spread apart tempo rarily and denergize the shunt magnet 69, the armature of which is drawn out of contact with the strip 73 by the spring 72, the shaft 54 being carried its full movement by the momentum of the moving parts.

The lost motion between the worm 48 and the gear 55, Fig. 2, is such that before this motion is taken up by the motor 46, there is likelihood o-f the lock controlling pawl 59 returning to lock the wheel 55, by the establishment of the shunt circuit, in which case the gearing would be considerably strained and twisted. In order to prevent this possibility, the following means is provided: Pivoted to the disk 57 is a pawl 97 which is forced into engagement with the rear end of the locking pawl 59 by a light coil spring 9S. Then the pawl 59l is drawn down by its magnet 61, the pawl 97 passes over its upper side and holds said locking pawl in its unlocking position. The forward movement of the pawl 97 is limited by a pin 99 mounted in the side of the disk 57. When the disk 57 is rotated, the pawl 59 rides upon its periphery, and near the end of rotation of the disk the pawl 59 cont-acts with the pawl 97 and forces it against the tension of its spring into the position shown in Fig. 2.

It will be seen from the foregoing description that,'when any one of the cash drawers is drawn outward, the circuit for that particular drawer will be closed by the mechanism located immediately back of the drawer. This closing of the circuit will energize the magnet pertaining to that particular clerks key, or plunger, which will effect the withdrawal of the latch and permit the key, or plunger, to project down into the path of the latching member carried by the differential segment. By this means the segment will be arrested by the projecting key, in a position bringing the proper indicator and the proper printing type into position. At the time this key circuit is closed, the unlatching magnet is energized which unlocks the machine; and the .shunt magnet is also energized which makes a circuit not including the contact points behind the Cash drawer so that as the wedge springs back and separates the contact points, the circuit is not broken and the motor continues in operation until its circuit is momentarily broken by the cam disk connected to the rotation shaft as before described.

It will be observed by reference to Fig. 4f, that after the shunt circuit is closed all of the key latch magnets, as well as the main machine locking magnet, are ineffective and the key latches are thus permitted to assume their normal latching positions. It will further be seen that the wiper arm follows directly behind the latch of the differential segment in each instance, so that after the latch has been arrested by striking the key, the continued upward movement o-f the wiper arm will immediately return the key to its normal position,` where it will be latched by its armature latch which is made again effective by the completion of the shunt circuit.

With the above devices the first operation of the machine is the opening of a cash drawer, but when any cash drawer is opened the operation of the machine is started and cannot be arrested by the operator. The opening of the cash drawer also determines, or selects, the clerks key, and this key moves to operating position before the motor gives the devices suiiicient movement to prevent the key from assuming an operative position. It will of course be understood that suitable alarms are controlled by the cash drawers in opening, so that one clerk cannot open the cash drawer of another without detection.

In operating a machine of this type the operator first depresses the proper amount keys; he then takes hold of the drawerpull of his proper cash drawer and with it draws the drawer out far enough to reach the coins in the front coin spaces; he then proceeds to make change, and before he has completed this transaction and closed the cash drawer the machine has completed its operation.
